Frequently Asked Questions
What formula does the calorie calculator use?
Most reliable calorie calculators utilize either the Mifflin-St Jeor equation or the Harris-Benedict formula. These equations estimate your Basal Metabolic Rate (BMR) and then apply a multiplier based on your physical activity.
Is it safe to consume fewer calories than my BMR?
It is generally not recommended to eat fewer calories than your BMR, as your body needs this minimum energy just to sustain basic life functions. Severe calorie restriction can lead to nutrient deficiencies and slow down your metabolism.
